Horizontal Grid Structure

The CAMx modeling domain is defined in the Lambert Conformal Conic map projection:

First True Latitude (Alpha):

30ºN

Second True Latitude (Beta):

60ºN

Central Longitude (Gamma):

100ºW

Projection Origin:

(100ºW, 40ºN)

Spheroid:

Perfect Sphere, Radius = 6370 km

The horizontal modeling domain structure consists of a coarse-grid East US domain and nested fine-grid subdomains: East Texas subdomain, Houston-Galveston-Brazoria/Beaumont-Port Arthur (HGB/BPA) subdomain, and the Houston-Galveston (HG) subdomains.
